Everything in this category

• AI Text Cleaner — Strip the giveaways from AI-written text: em dashes, curly quotes, hidden characters and the phrases models overuse.
• AI Writing Tells Analyzer — Measure the stylistic markers associated with AI writing — dash density, sentence uniformity, overused phrases. Not a detector.
• Chat Transcript Formatter — Turn a copied chat conversation into clean markdown, JSON messages, or a plain transcript.
• Edit Diff Summary — Compare a draft with its rewrite and see exactly what changed, word by word.
• Em Dash Remover — Replace em dashes with commas, periods or plain hyphens — the fastest way to make AI text stop looking like AI text.
• Emoji Remover — Strip emoji from text, including the multi-part sequences that other tools leave half-deleted.
• LLM Cost Calculator — Work out what an API workload costs per call, per day and per month, at your own prices.
• LLM Token Counter — Estimate how many tokens a prompt will use, and how much of a context window it fills.
• Markdown to Plain Text — Strip the markdown formatting out of AI output and leave clean, pasteable prose.
• Prompt Formatter — Wrap prompt sections in XML-style tags, the structure models follow most reliably.
• Prompt Template Filler — Fill {{variables}} in a prompt template from a list of values, and generate every version at once.
• Smart Quote Converter — Convert curly quotes, dashes and ellipses to plain ASCII — or back the other way.
• System Prompt Builder — Assemble a structured system prompt from role, task, rules, format and refusal behavior.
